&
Location

Re-excavation of the following beels are required                     1. Gochina beel
2. Magra beel (1km long 81 hight)
3. Khusaldaha beel
4.Singrail beel

Sreerampur dam to be constructed (1km - long, 8'height) one dam near Rainagar has been constructed for flood protection measure. (100 (m) long, 8' height)

---

4/5 Sluice gates to be constructed at Purba Mathurapur near BSF Camp. 4 hume pipe gates have already been constructed at the breach points at Sreerampur.

Effectiveness of above measures

A qualitative perception with regard to effectiveness of existing remedial measures may be given in brief.

Ther was no flood after 1995. Re-excavation of beels and Sreeriver/Ghola Khari, construction of Small check bundh and construction of 4/5 hume pipe culverts as suggested will minimise the impact of flood.

Suggested Solutions.

Re-excavation of Sree river/Ghola khari, Gochina beel, Magar beel, Khusaldaha beel, Singrail beel, construction of small check dam at Sreerampur. Construction of 4/5 hume pipe culverts at Purba Mathurapur
